This patch series adds support for disabling the generation of h/vsync signals
on the ti-sn65dsi83 bridge.

This is required on some panels which are driven in DE-only mode but do not
ignore sync packets, and instead require them to be low-voltage level or ground.

A discussion (1) on TI's E2E forum confirms that this may be required for some
panels.
